Fabrics...

With the exception of some Rogue Panda bags that I absolutely love, I make all of my own bags. i.e. Frame, handlebar, feedbags, etc...
I'm getting ready to remake a roll bag that fits my Jones H-Bar. The way that I make them, the straps wrap around the bars in a few spot which holds the handlebar bag snug to the H-bar. There is no shake or wobble at all. In the past, I've used 1.9 ounce ripstop fabric which works well for the dry bag part of the system, but I am looking to go a little heavier this time. It got me looking at X-Pac, Dyneema and regular heavy nylon. I've even seen some polyester ripstop but I do not know how waterproof that it would be.
Any fabrics that you might recommend?

I am using pvc 620 density. Since there is no padding, seals, etc., the weight is more, but not much. Moreover, the bags are 100% waterproof. You can see my work on Instagram "Bike and Bags" Or here, but less https://bikeandbags.eu/foto-robit/
